Abstract: 1442787 Ignition systems ELTRA CORP 5 Dec 1973 [10 Jan 1973] 56270/73 Heading F1B [Also in Division H2] In a capacitor discharge type ignition system wherein a notched eccentrically shaped permanent magnet rotor member 19 periodically induces a two-peak voltage waveform Fig. 1b in each of two stator pick-up coils 31, automatic advance of the timing is obtained by using one peak as a firing trigger at low speeds, and the other at high speeds. In the arrangement shown, the member 19 comprises a permanent magnet ring 28, in the form of a ferritic loaded elastomer, and inner/outer soft magnetic rings 27/29, all on a shaft 10, the ring 29 being constituted by two tapering cross-section half-rings. The half-rings are mounted with their wide ends spaced to form a gap A, and their narrow ends spaced to form a gap B, and the leading one is provided with a notch C which tapers from a greater depth at the leading edge to a lesser depth at the trailing edge adjacent gap A; the eccentricity of the ring 29 and the presence of the notch and gaps therein thus cause the flux in each coil 31 to be as in Fig. 1a, and the voltage output as in Fig. 1b. In the firing circuitry Fig. 4, two SCR's 43, 44 are arranged to be triggered only by the larger, later, voltage peak in each cycle for low engine speeds, a capacitor 40 discharging through two output pulse transformers at the spark-plugs; at high engine speeds however, the earlier voltage peak becomes sufficient to fire the SCR's, and the timing advances. The capacitor 40 is charged by one or other of two stator coils 18a, 18b energized by magnets 16 of a further rotor member 14. Additional coils 18 provide power for lighting &c. If the system is run in reverse the induced voltage pattern Fig. 1d is such as to prevent firing.
